Saturated and unsaturated
Spinning rides at a carnival or amusement park are thrilling because of a center-seeking force called what?
Centripetal force
This biochemical is important for building body tissues, regulating life processes, and keeping your immune system strong.
Protein
From what source do plants get their energy during photosynthesis?
Sun/sunlight
This biochemical reaction involves releasing energy from food.
Cellular respiration
In the experiment we conducted with the fruit juices, the juices that turned the iodine solution clear in the fewest number of drops contained the (MOST) or (LEAST) amount of vitamin C?

This branch of science combines the study of physics and biology to examine cells, organisms, and ecosystems.
Biophysics
What is known as a type of sugar that behaves as the major source of energy for the cells in our bodies?
Glucose
Most of of organic nutrients are not produced in our bodies so we must get them from food. What are they called?
Vitamins
This is one of the most important biochemical reactions because it is involved in the making of food.
Photosynthesis
What is formed when many glucose molecules bond together?
The complex molecule known as starch
What is known as a chemical process that adds hydrogen atoms to unsaturated hydrocarbons and lipids?
Hydrogenation
These are known as reaction helpers that speed up reactions inside cells without being used up.
Enzymes
What is the name of the scientist who discovered that the pressure of a moving fluid decreases as the fluid moves faster?
David Bernoulli
True or false: The products of photosynthesis are the reactants of cellular respiration, and vice versa.
True
